[Browser] How to know when setURL has finished [message #645541]

I'm trying to use the SWT Browser widget to do some junit testing. The first thing I need it to do is load a URL. So, how can I know when the browser has finished loading that URL and I can start asking it to evaluate snippets of javascript needed to kick of the tests?

I tried adding a progress listener, setting the URL, and waiting for the "complete" callback. That seemed to work with Safari (although maybe I got lucky). But there seem to be multiple "complete" events, and waiting for the first one failed with IE. When I called Browser#evaluate(), the page's javascript hadn't yet been evaluated.

This seems like such a simple thing to do. Has anyone figured out how to know when the browser has finished loading the page?

Hi Randy, sorry for the late reply,

Listening for completed() is the right thing do to here, only one of these
should be received for a page load. Perhaps the first one coming in is
triggered by something like a XHR completion? Please log a report with swt
and this can be investigated.
